This paper investigates the penetration levels of PV systems in distribution feeders by taking into account the mutual coupling effect among phase conductors. The increase of the allowable PV penetration by executing transposition of phase conductors to improve the three phase balancing is also analyzed. The equivalent circuit models for three-phase, two-phase and single-phase conductors including the earthing effect and the mutual coupling between phase conductors and grounding wire are applied in the computer simulation. A practical Taipower distribution feeder is selected for system analysis to solve the maximum PV penetration with the proposed precise modeling of a feeder network. It is found that the maximum penetration level of considering mutual coupling effect is less than that of without considering mutual coupling effect.
